The GermGuardian GG1100B is a plug-in air sanitizer that uses UV-C light to reduce airborne bacteria, viruses and mold spores and to cut odors from pets, smoke, cooking and mildew. It has no filters to replace and no setup: it goes straight into a wall outlet. It suits small, enclosed spaces like bathrooms, laundry rooms and pet areas. Against filter-based purifiers it is cheaper to run and quieter, but it moves little air and its cleaning effect is limited to the light chamber, so it is a supplement to a room purifier rather than a replacement.
